After reinstalling Poser the application crashed really bad. After the next install and trying to use the Crop Tool I get the message:

:Can't complete the request because all Scratch disks are full".

I have GB of free disk space on my C drive.

I don't know how to make it work again. In Preferences the Scratchdis is set to C: but it seems PS ignores it. Something got corrupted and I can't find it. Can somebody please help?

Operating system is XP.
